[0023] Specifically, the motor 110 drives the sprocket 120 to rotate, and the sprocket 120 meshes with the chain 130, thereby converting the rotary motion of the sprocket 120 into the reciprocating linear motion of the chain 130. When the chain 130 moves linearly along the extension direction of the chain 130, the first fixing member 140 and the second fixing member 150 also move with the chain 130. The present application uses the sprocket 120 and the chain 130 for transmission without elastic sliding and slipping, and has the advantages of accurate transmission ratio, reliable operation, high efficiency, large transmission power, strong overload capacity, and the ability to work in harsh environments such as high temperature, humidity, dust, and pollution.

[0024] Among them, the chain 130 in the present application is not tensioned and fixed by the sprockets 120 at both ends, but the two ends of the chain 130 are fixed to the first fixing member 140 and the second fixing member 150 by screws or other structures. The structure is simple and efficient, easy to maintain, and the linear motion of the chain 130 can realize the movement of the load part, and the pushing and pulling are stable and highly practical.

[0025] The motor 110 can be a servo motor, a stepper motor or other motors with low maintenance costs. The servo motor 110 controls the rotation angle of the motor output shaft by controlling the duration of the pulse, while the stepper motor 110 controls the rotation angle of the motor output shaft by controlling the number of pulses. The motor 110 needs to be repaired due to acid corrosion in the electroplating environment, thereby reducing the maintenance cost.

[0026] It can be seen from the above content that the push-pull mechanism 100 of the present application includes a motor 110, a sprocket 120, a chain 130, a first fixing member 140 and a second fixing member 150.

The motor 110 drives the sprocket 120 to rotate, and the sprocket 120 is meshed with the chain 130, thereby converting the rotary motion of the sprocket 120 into the reciprocating linear motion of the chain 130. When the chain 130 moves linearly along the extension direction of the chain 130, the first fixing member 140 and the second fixing member 150 also move linearly along the extension direction of the chain 130. In the present application, both ends of the chain 130 are fixed to the first fixing member 140 and the second fixing member 150, which has a simple and efficient structure and is easy to maintain.

The surface of the pressing tooth 180 is provided with a toothed structure, and the pressing tooth 180 meshes with the chain 130, thereby generating a friction force, pressing the chain 130, and preventing the chain 130 from sagging and shaking during the transmission process, thereby ensuring the stability and reliability of the transmission of the chain 130. Among them, the toothed structure can be designed according to the specifications of the chain 130, and common toothed structures include straight teeth, helical teeth, herringbone teeth, etc., which are not limited in this application.

The limiter 192 may be in a rectangular or circular shape, for example, and the sensor 193 may be a photoelectric switch, a magnetic induction switch, an inductive switch, for example. When the guide rod 190 moves to the point where the distance between the limiter 192 and the sensor 193 is less than a distance threshold, the sensor 193 generates a trigger signal and transmits the signal to the motor 110, causing the motor 110 to stop rotating, thereby stopping the push-pull mechanism 100, and realizing that the push-pull mechanism 100 moves the load to the target position, wherein the distance threshold is set by the staff.
